RESILIENT WHEEL.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed December 3. 1919. Serial No. 342159.

To all whom it may concern:

Be it known that I, J 101m V. .HEADLEY, a. citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, haveinvented certain new and useful Improvements in Re silient Wheels, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in resilient wheels, and it. is an object of the invention to provide a device of this general characterwith novel and improved means whereby the same effectually absorbs the shocks and jars incident to'the travel of the vehicle to which it is applied.

It is also an object ofthe invention to provide a novel and improved wheel of this general character wherein the shock absorbing agencies comprise a plurality of suitably mounted springs coacting with both the hub and the felly of the wheel structure.

The invention consists in the details of construction and in the combination and ar j wheel constructed in accordance with an embodiment of my inventidn;

Fig. 2 is a fragmentary sectional view taken through the structure, as illustrated in Fig. 1;

Fig. 3 is a fragmentary sectional view tion, and,

Fig. 4 is a fragmentary sectional view illustrating a still further modified form of invention. 7

As disclosed in the accompanying drawings, H denotes a hub, preferably of wood, and provided at one end with a reduced extension 1. Snugly fitting to and extending around the periphery of the hub H is an annular member or band 2, provided with two transversely spaced and circumferentiallv disposed series of cups or pockets 3.

Surrounding the hub H, and substantially concentric thereto when the wheel is free of load, is an annular member 4 of a width substantially equal to the combined length of the hub H and extension 1 thereof. The inner face ofthe member 4 is provided with the cups or pockets 5 substantially in radial almement with the cups or pockets 3. Interposed between the hub H and the member 4 is the shock absorbing agency herein disclosed as comprising a plurality of expansible members 6, preferably coil springs. Each of said members or springs G has one end portion seating within a cup or pocket 3 of the hub H, and its opposite end portion seating within the cup or pocket 5 of the member 4, and substantially in radial alinement with the first named cup or pocket 8.

The extension 1 has also snugly engaged therearound an annular member '7 provided with the circumferentially spaced cups or pockets 8 in radial alinement with the supplemental cups or pockets 9 carried by the adjacent side portion of the annular member 4. Seating within the pockets 8 and 9 are the expansible members or coil springs 10, which provide a further shock absorbing agency for the member 4.

,Side plates 1-1 extend inwardly from the sides of the member 4, and are provided with the annular grooves 12, to receive the edges of the member 4.

The plates 11 are held to the member 4 by the clamping bolts 14, coacting therewith, and extending transversely of the structure. An intermediate portion of each of the plates 11 extends inwardly, as at 15, and contacts with the outer face of the member 4, and from said portion 15 the plate 11 extends outwardly a predetermined distance.

Secured to each of the plates 11, preferably by-the bolts 14, is the inner marginal portion ofa bracing or reinforcing plate 16, which extends inwardly, and is secured to the outer marginal portion of the plate 11 by the bolts 17, and which bolts also connect the outer portions of both of the plates 11.

The reinforcing plates 16 have their outer portions lS'extending beyond the plates 11, with the opposed faces of said portions 9, and in parallelism in cross section. Fitting between theportions 18 is the felly 19. Suitably secured to the side faces of the felly 19 are the annular plates 20, preferably of brass, which have sliding contact with the annular plates 21, preferably of steel, carried by the opposed faces of the portions 18. The coaction of the plates 20 and 21 is such as to materially facilitate the relative movements between the felly 19 and the hub H, or the member 4. V.

.Interposed between the felly 19 and the member 4 is a shock absorbing agency disclosed as comprising a plurality of circumferentially spaced expansible members or coil springs 22. One end of each of the springs 22 seats within a cup or pocket 23,

7 carried by the outer face of the member 4,

acting therewith only and the opposite end of said member or spring seats within a pocket or recess 24, carried by the inner face of the felly 19. The felly 19 has mounted thereon a tire T,

which may be of metal, hard rubber or of any character preferred. As the structure of the tire T in itself forms no particular part of my invention, a detailed description thereof is believed to be unnecessary. The central opening defined by the outer plate 11 has disposed thereover a hub cap 25, suitably fixed to said plate 11.

. In the form of my invention, asparticularly illustrated in Fig. 3, the hub H has cosprings 6, and only a single reinforcing or bracing plate 16'.

In the embodiment of my invention,as particularly illustrated in Fig. 4, the portions 18 of the side plates 11 have arranged therebe movement of said felly between the portions 18;. This same structure is present in the two modified forms ofaconstruction herein described and illustrated.

From the foregoing description it is thought to be obvious that a resilient wheel constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it maybe assembled and operated, and

it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for thisreason I do not wish to be understood aslimiting myself to V the precise arrangement and formation of the several parts herein shown in carrylng a single series ofv out my invention in inafter claimed.

I claim:
